To all whom it may concern:

Be it known that we, EDMUND W. DEH- LER and MARY DEHLER, citizens of the United States of America, of Syracuse, in the county of Onondaga in the State of New, York, have invented new and useful Improvements in Car Trucks, of whichthe following, taken in connection with the accompanying drawings, is a full, clear, and exact description.

This invention relates to a railway car truck involving the use of a symmetrical frame and a pair of parallel axles journaled therein and each provided with a pair of flanged wheels adapted to roll along the track.

The side plates or sills and cross bars commonly employed in trucks of this character are frequently made of cast iron or specially molded designs requiring re-enforcing ribs and flanges formed integral therewith, all of which adds greatly to the weight and cost of. the truck without remov ing the inherent liability of breakage espe- I cially in freezing climates.

The main object of the present invention is to produce a comparatively light, strong and durable truck by constructing the major portions of the frame from boiler iron or sheet steel commonly carried in stock and capable of being stamped or cut to the de sired form and size in a single punching operation which enables the parts to be easily and quickly assembled without special machine work and thereby greatly reduces the cost of manufacture and at the same time, increasing the production or output for a given period of time.

Another object is to make the side plates or sills of uniform size and shape so that they may be stamped by the same dies and may be used at either side of the truck or reversed end for end.

Another object is to connect the ends of the side plates or sills by suitable fenders or bumpers of boiler iron or sheet steel and to make said fenders of the same form and size so that they may also be interchanged or reversed end for end when applying them to the side plates.

A further object is to reduce the weight of the side plates or sills by cutting away the central portions thereof and leaving integral connecting portions above and below the openings for bracing purposes.

Another object is to re-enforce the upper Flgure 1 is a perspective view of a railway car truck embodying the varlous feaf tures of our invention.

Figure 6 is a perspective view of one of the yokes for bridging the underside of the openin for one of the guide openings in the side plate or sill, and Figure 7 is a perspective view of the opposite halves of one of the journal bearings adapted to be placed H 3-- at the lower sides of said openings,

but of less vertical height than the portions of the plates above the openings thereby reducing the weight of the plates and at the same time maintaining suflicient strength to resist the strains to which the plates are subjected.

The portions of each plate --1 at opposite ends of the opening -9/- are provided with vertical slots or openings 4-- extending upwardly from the lower edge thereof and at right angles thereto for receiving separate pairs of upright guide plates 5, top plates 6 and journal boxes -7 hereinafter more fully de scribed. I

The opposite ends of the side plates are substantially identical in that they extend the same distance-beyond theopenings-re and are preferably tapered edgewise' vertically tothe san e form and size to to "111 convenient n eans vfor attachingopposite end fendersor bumpers +8.- thereto.

opening -15, the outer end of said opening being reduced in size to form a stop shoulder -17- for limiting the outward movement of the journal sections 16- and -16.

As previously stated, the truck frame is adapted to receive a pair of parallel axles -18 each having a pair of flanged wheels --19, the outer ends of each axle being reduced in diameter and journaled in the adjacent bearings -16 and 16 and forming shoulders 19 which are engaged with the inner ends of said bearings to hold the latter against inward displacement and against the shoulders -17-.

The outer ends of the openings -15 in the journalboxes 17- are normally closed by cover plates 20- which are pivoted at -21 to the upper portions of the boxes to permit them to swing in vertical planes to and from their closed positions so that when closed they form oil pockets 22 for lubricating the journal bearings for the axles.

Suitable coil springs --23- are interposed between the upper faces of the journal boxes -7- and lower faces of the top plates 6- to yieldingly support the frame bars -1 and body of the car mounted thereon.

The axles 18- with the wheels and journal boxes thereon may be placed in operative position in the openings of the frame bars -1- through the open lower ends thereof after which the yokes 1 lmay be secured in place to hold the journal boxes 7 and frame bars against relative vertical displacement, and for this purpose each yoke is U-shaped in side elevation and has its opposite arms bifurcated or slotted at -24 to receive the lower edges of the frame bars 1 at opposite ends of its opening 4, said arms and adjacent portions of the plate 1 being provided with registering bolt openings for receiving bolts -25 by which the yo-kes are firmly secured in place with the bottoms of the slots 2 l seated snugly against the lower edges of. the side plates 1 and the journal boxes -7-- yieldingly held against the underlying portions of the yokes by the springs -23.

The operation of our invention will be understood upon reference to the foregoing description and the acompanying drawing.

and it is evident that a structure of this character is particularly light, strong and durable and may be manufactured at a comparatively low cost and at the same time is free from any of the objectionable ribs and re-enforcing projections commonly employed in cast metal truck frames.

We claim:

1. In a railway car truck, a frame comprising a pair of fiat sheet metal side plates arranged edgewise vertically and each of uniform thickness throughout its area and provided with a pair of transverse openings extending upwardly from its lower edge at equal distances from its ends, in combination with journal. boxes movable in said openings and yokes extending across the undersides of the journal boxes and provided with slotted arms engaging the inner and outer faces of the plate at opposite ends of their respective openings.

2. A railway car truck as in claim 1, in which the side plates are provided with similar transverse openings between the first openings and intermediate the lower and upper edges of said plates, the plates being continuous across the lower and upper sides of the second named openings.

3. A railway car truck as in claim 1, in which angle irons are secured to the inner faces of the side plates above the transverse openings.

4:. In a railway car truck, a frame comprising a pair of fiat sheet metal side plates arranged edgewise vertically and each of uniform thickness throughout its area and provided with a pair of transverse openings extending upwardly from its lower edge at equal distances from its ends for receiving journal boxes for the axles, and angle irons secured to the inner faces of the side plates with their upper sides substantially coincident with the upper edges of said plates and their opposite ends extended over the transverse openings.

In witness whereof we have hereunto set our hands this 2nd day of Feburary, 1924.
